A composite-forming process includes impregnating a reinforcing structure with a curable composition at a temperature of about 10 to about 40° C. The curable composition includes specific amounts of an epoxy resin, a poly(arylene ether), a solvent, and a curing promoter. The poly(arylene ether) includes, on average, about 1.6 to about 2.4 phenolic hydroxy groups per molecule, and it has a polydispersity index less than or equal to 2.2 and an intrinsic viscosity of about 0.03 to about 0.2 deciliter per gram. These characteristics substantially improve the solubility of the poly(arylene ether) in the curable composition and allow the curable composition to be formed and used at or near room temperature. Composites formed by the process and circuit boards including the composites are also described.

A curable composition includes an olefinically unsaturated monomer and a poly(arylene ether) having two polymerizable groups and an intrinsic viscosity of about 0.05 to about 0.30 deciliters per gram. The composition exhibits an improved combination of high flow during molding and high post-cure stiffness and impact strength. The composition is particularly useful for fabricating plastic-packaged electronic devices.

The invention also provides a biodegradable polyester / starch composite material containing the thermoplastic starch and a preparation method thereof.

Provided is a production process for polyarylene sulfide having a high molecular weight and an excellent heat stability. It is a production process for polyarylene sulfide by reacting a dihalogenoaromatic compound with metal sulfide in a polar solvent, wherein all or a part of water required for the reaction is added on a condition that the reaction system is 100° C. or higher, whereby obtained is polyarylene sulfide which is reduced in an intrinsic viscosity [eta] by 0.05 deciliter / g or less at 206° C. when added to an N-methyl-2-pyrrolidone solvent is the polyarylene sulfide of an amount equivalent to the solvent and it is maintained at 265° C. for 8 hours.

A varnish composition for producing an electrically insulative thermoset coating is disclosed. The varnish composition includes a functionalized poly(phenylene ether) having at least one aliphatic unsaturated group and exhibiting an intrinsic viscosity in the range of about 0.06 to about 0.25 deciliter per gram, measured in chloroform at 25° C. The varnish composition further includes an unsaturated polyester resin or vinyl ester resin, a reactive liquid monomer, and a compatibilizing agent. When cured, the polymers and reactive liquid monomer form an electrically insulative thermoset.

A method having clinically sufficient degree of diagnostic accuracy for detecting the presence of coronary artery disease in a human patient from the general population and for distinguishing between the stages of the disease in that patient is disclosed. The stages are, first, the non-acute stage, which is either asymptomatic coronary artery disease or stable angina, second, the acute stage known as unstable angina, and, third, the acute stage known as acute myocardial infarction. The diseased state (as opposed to the non-diseased state) is indicated by the clinically significant presence of a first marker in a sample from the patient. The presence of one of the two acute stages, unstable angina or acute myocardial infarction, is indicated by the clinically significant presence of a second marker in a sample from the patient. The presence of the more severe acute stage known as acute myocardial infarction is indicated by the clinically significant presence of a third marker in a sample from the patient. Preferably the first marker comprises OxLDL, the second marker comprises MDA-modified LDL, and the third marker is a troponin. Preferably the OxLDL and MDA-modified LDL are detected using monoclonal antibodies that can detect the presence of those markers in undiluted human plasma at concentrations as low as 0.02 milligrams / deciliter.

A process for preparing a redistributed poly(phenylene ether), comprising reacting a poly(phenylene ether) in a reactive diluent monomer with a polyhydric phenol in the presence of a redistribution catalyst to form a composition comprising a redistributed poly(phenylene ether) in the reactive monomer diluent. The redistributed poly(phenylene ether) exhibits an intrinsic viscosity in the range of about 0.06 deciliters per gram to about 0.25 deciliters per gram, measured in chloroform at 25° C. The redistributed poly(phenylene ether) can be functionalized and admixed with unsaturated resin such as an unsaturated polyester resin or vinyl ester resin to obtain a varnish composition that, when cured, can form an electrically insulative thermoset.

A pharmaceutical composition for therapeutic administration of pyrophosphate for phosphate repletion may be in either liquid or solid form and may be usable as or usable for preparing a hemodialysis or peritoneal dialysis solution containing a pyrophosphate compound present in an amount that provides a concentration in the dialysis solution equivalent to an inorganic phosphorus concentration of at least 0.5 mg per deciliter.
